FSA Reporting how to tell if the FSA Agent installed on proxy server

We have been running EV for some time, but have tried recently setting up Reporting.  When I "Run FSA Reporting Scan" from the Admin Console, nothing happens.  It never shows it starting.  As our fileservers are Netapp, we have setup a proxy server. 

My question is how can I tell if the FSA Agent is installed on my Proxy server, and will it hurt anything to reinstall?  Would it be best if I shutdown services prior to re-installing the FSA Agent?

Thanks,

Linda
